easily combined with the push-buttonron a house, has simple electric control, andiabove all isA extremely economical to manufacture. i Further object-s of the invention will be pointed out more in detail in the accompanying claims which are Vdirected to an illustrative embodiment of the invention shown in the accompanying drawings solely for purposes ofillustration and not in limita tion.

In the drawings- Fig. 1 is a front elevation, partly in section and partly diagrammatic, of the invention associated with 'a push button; and

Fig. 2 is a horizontal section through the embodiment of Fig. 1. v y

A sheet metal frame A isconstructed preferably of rectangular configuration with struck-out integral flanges 1, 2, 3 and 4 for the reception of screws 5 vfor the purpose of attaching the same to a building wall 6. The flanges 1, 2, 3 and 4 project out at right angles respectively from the side walls 7 8, 9 and 10. At the front of the frame, inturned flanges 11, 12, 13 and 14 are provided as retaining means Vfor a translucent window B. In its preferred construction this window comprises a sheet of plain glass 15 to lit the window opening, opaque or contrasting display characters 16, and a rear covering 17 of colored translucent material such as colored crpe paper pasted at its edges to the glass. By this construction inexpensive glass may be employed such as ordinary window glass while all the colored part and the display and the characters are protected. Y

A suitable socket 20 to mount an electric bulb 21 is itself mounted in the frame as, for example, in the wall 7. It is preferred that this Vsocket itself have an electric connector 22 for cooperation with'the plug or pin 23 forming the terminal of a flexible connector extending from one terminal 25 ofthe bell ringing circuit, whilethe other leg of the local circuit for the bulb 21 is provided through means of the connection 26 extending from the other terminal 27 of the bell ringing circuit. The mounting of the bulb 21 is thus mid-positioned between the front and back of the frame A. The bulb should be selected so as not to ring the door bell and to -accord with the voltage of the ringing circuit. The plug 23 extendsV out of the connector 22 for easy and frequent manipulation. This serves as the switch to control the circuit for the bulb 21. l

A cylindrical-shaped or bowed strip of sheet metal 30 with its face 31 covered with some light-diffusing material such as aluminum paint is bent so as to tend to occupy a horizontal space greater than the space between the window and the building wall so ythat it will be compressed. It has preferably out-turned bearing edges 32 and 33 adapted to press through the spring urge inherent in the strip 30 itself against thewindow 15 to hold the saineV in place against the reaction of the fianges 11, 12, 13 and 14. In this way both the plate 30 servingfas a reflector is properly mounted in position, and, at the same time, the window is firmly held to vform a` tight outer closure. If desired, gaskets may be provided between the rim of the window and the flanges 11, 12, 13 and 14. This and the flanges 1, 2, 3 and v4.

The inventive thought may have a variety of expressions is contemplated by what I claim and desire to secure by United States Letters Patent as' follows is likewise true between the building wall 1. An illuminated signl adapted for combiy nation with the front door bell electric circuit of houses comprising an outstanding frame open at the front; `a translucent display window adapted lto close said front; retaining means for said window formed Von said frame to .resist outward movement of Y said window; a resilient combined reflector and holder of bowed configuration with its concavity towards said window and with its ends terminating short of 'the sidewalls of said frame, the natural bow-in said holder being of a depth greater than the depth of said frame; means for mounting said frame so as to hold said holder resiliently flexed with its ends forcibly thrusting outwardly to press said window firmly against said retaining means; an electric light .bulb socket between said combined reflector andV holderv i and said windowg'and electric connections for supplying current to said socket.

. 2. In illuminated signs, a rectangular l metal frame open atk the front and the back;

attachingflanges at the rear of said frame adapted to fasten the same to the vertical face of a house; window retaining flanges llll'.

at the frwa'rd part of said frame.; a transthe face of said' house and sai'fclf window t0 hold said Window rmly in place and servingr as a reflector. v

En Witness. whereof, I have Signed my naine t0 this specification this 31st Clay of 4Marcha 1924.
